Nonetheless, it is to be appreciated that aspects of the present invention are also equally applicable to other like applications, devices, and methods of manufacture.

BACKGROUND

By way of background, billiard is a sport in which a billiard ball is hit by a billiard cue stick on a billiard table. Generally, a bridge is formed by one hand to fix the cue, and the other hand is used to move the pool cue stick to hit a ball by applying force to the pool cue stick. A billiard cue stick is a long wooden pole that a billiard player uses to hit a billiard ball. Typical billiard or pool cues are two piece cues comprising a tip, a ferrule, a collar, a joint, a pin, a ring, a forearm, a wrap, a sleeve, and a bumper. The pool cue shaft comprises the top section and includes the section extending from the tip to the joint. The pool cue butt comprises the base section and includes the section extending from the pin to the bumper. The tip is the only part of the pool cue that touches the cue balls.

Conventional billiard cue sticks are generally long and sufficient open square footage space around a billiard or pool table is required for effective movement of the pool cue stick for hitting a ball. However, in crowded pool halls where pool or billiard tables are placed relatively near to each other, players may lack sufficient space for extending and manipulating conventional pool cues while playing. Furnishings, walls, and other obstacles can be in the way when using a standard length billiard cue stick. This leads to inefficient practice and missed shots, and players may become disappointed with their current skill level and/or become frustrated with the present layout of the billiard table.

Another disadvantage of present billiard cues is that they are manufactured at a limited number of lengths and weights due to potentially high manufacturing and inventory costs. It is therefore desirable to provide billiard cues that can be customized in length, particularly for play in crowded halls and small rooms thereby enabling shooters to play at competitive levels. The selectively adjusted cue length is also desirable to accommodate different sized players (i.e. from adult to child).

Therefore, there exists a long felt need in the art for a billiard cue stick that can expand and retract to various length options. There is also a long felt need in the art for a cue stick that enables users or shooters to play in crowded pool halls, or in limited room spaces, at a competitive level. Additionally, there is a long felt need in the art for a billiard cue stick that is lightweight and has prolonged durability. Moreover, there is a long felt need in the art for a cue stick that can be used in minimal space while providing functionality of a conventional cue stick. Further, there is a long felt need in the art for a cue stick that can be manually adjusted in length. Furthermore, there is a long felt need in the art for a cue stick that can be selectively or electrically adjusted in length. Finally, there is a long felt need in the art for a billiard cue stick that offers a way to use the pool cue stick in virtually any situation or space for a variety of shooter sizes by adjusting a length of the pool cue stick.

The subject matter disclosed and claimed herein, in one embodiment thereof, comprises an expandable billiard cue stick. The pool cue stick features a spring-loaded mechanism including an extendable tension rod with fixed metal pegs, a button positioned on the pool cue stick, the button when pressed is configured to release pressure from a spring enabling the pool cue stick to expand or retract. The metal pegs have corresponding receiver holes wherein the metal pegs are locked in the corresponding receiver holes to lock the pool cue stick to a desired length. Alternatively, the pool cue stick can have a cranking mechanism using a segmented screwdriver system that can be manually or automatically cranked for adjusting the length of the pool cue stick.

In this manner, the adjustable or expandable billiard cue stick of the present invention accomplishes all of the forgoing objectives and provides users with a multipurpose adjustable and lightweight cue stick that enables players to expand and retract the length of the pool cue stick as per their preferences. Further, the pool cue stick can includes a spring-loaded mechanism to lock the pool cue stick to a desired length or a cranking mechanism to adjust the length of the pool cue stick. The pool cue stick can be used in various length options while maintaining the pool cue stick's playability and functionality.
